Hi everyone,
I wanted to give the latest update with a better Antenna hooked up to the FM3 tuner I got last week. Well, the first time I hooked it up with just a regular cheap 300 ohm antenna. The reception was good but not great do to some back ground hiss on some station and some sibliance on others.
Today I finally connected my FM3 to my Magnum Dynalab FM2 antenna with the arrival of my Balun. The FM3 sounds a lot better and more quiet on all stations with no back ground hiss when it's tuned in for max reception and all that sibilance is now gone. Sound quality is really nice and like others have said the mids are really nice with good bass. Highs seem there but are a little rolled off but nothing crazy to keep me from enjoying the little tuner. This tuner has good depth in soundstage. So from this first change in antenna quality, this FM3 responds quite well to better antennas.
I'm just enjoying this tuner for now until I can connect my Rhombic Antenna that I some how misplaced. The weird part is I just seen it last month when I was looking for something else. It's here, I just need to find it. Then I will now what this tuner in stock condition can really do.
One thing I noticed that the station dial and the station I'm listening to don't line up properly. The station comes in clear and strong but on the dial it's like .5 off for the actual station. so when the station says 101.5 FM it actually is closer to (almost right on) 102 FM on the dial. So this may need alignment which is ok since I will be doing the upgrades on it and then I can send it to Mike Z for alignment.
Now, onto the upgrades and modules. I have been having a hard time getting any response from FM3 Zone or SDS. I will keep trying and see what happens or I will just make my own PCB's with the upgrades. I will be installing some Jensen Copper Foil PIO caps in the output section. I like the way these sound and will be my first choice. If they don't work for me which I doubt, my next choice will be the Audyn TRUE copper caps.
btw, has anyone here removed the volume/stereo pot on the front panel and bypassed it? I would think this would lead to a big increase in sound quality with the pot out of the circuit.
Hopefully I can find the Rhombic this weekend so I post back on how this FM3 tuners sound with the better directional antenna that the Rhombic is and can give Timbo the results that he is waiting for! :)
back to listening to the FM3!
